In this first post – I’ll discuss various aspects of the interview questions. I’m sure some people like this approach for providing helpful hints and thought provoking questions, and others might dislike this approach because they feel it is nothing more than cheating. So I have decided not to post the answers here and I wanted to encourage the readers to find the answers. There is plenty of material available to find these answers through QlikView Training, Reference Guide, White Papers, QlikView Community and other QlikView Blogs. So I’d encourage you to make the effort of finding the answers and learn the concept. I’ll keep adding questions…so stay tuned. Happy learning!
Please note : These are just potential questions and by no means these questions will help you to get a job or succeed in your role. I’d strongly encourage you to spend time to learn QlikView instead of depending on these questions. This is just my personal repository of Questions. Good luck!
